I believe that fibro is actually Lyme disease, a bacterial infection, generally gotten from the bite of an infedted tick.. IThe bacteria goes for our nerves and soft tissue. Rashes is part of the syndrome. possibly the body's way of trying to expel toxins being generated by the bacteria. . Go to www.lymenet.org/FlashDiscussion/MedicalQuestions and read up on it. www.Igenex.com is a good testing lab. It's best to work with a Lyme-treating doctor. The folks at lymenet can help you find one. You can also email me at [email protected].com to discuss.
